2 years ago a father was 4 times as old as his son. 3 years from now the father will be only 3 times as old as the son. how old is each now?
\n" ); document.write( "===================
\n" ); document.write( "Let father's age NOW be \"f\":
\n" ); document.write( "Let son's age NOW be \"s\"
\n" ); document.write( "--------------------------------
\n" ); document.write( "Equation:
\n" ); document.write( "(f-2)=4(s-2)
\n" ); document.write( "Equation:
\n" ); document.write( "(f+3)= 3(s+3)
\n" ); document.write( "-------------------
\n" ); document.write( "Simplify both equations:
\n" ); document.write( "f = 4s -8+2
\n" ); document.write( "f = 4s-6
\n" ); document.write( "and
\n" ); document.write( "f = 3s+9-3
\n" ); document.write( "f = 3s+6
\n" ); document.write( "-------------------
\n" ); document.write( "Equate the two expressions for \"f\":
\n" ); document.write( "4s-6 = 3s+6
\n" ); document.write( "s = 12 yrs old (son's age NOW)
\n" ); document.write( "---
\n" ); document.write( "Substitute into f = 3s+6 to solve for \"f\"
\n" ); document.write( "f = 3*12+6 = 42 yrs old (father's age NOW)
\n" ); document.write( "==============================================
\n" ); document.write( "Cheers,
